From my understanding, the thread pool has by default 25 threads(point to
note timers use the thread pool) that you can use. After all these threads
are used up the next request will wait until one of the threads becomes
free. The Pool is created the first time you

A) a timer is registered
B) you invoke the Threadpool.queueuserworkitem

To use the threadpool you need to call the Threadpool.queueuserworkitem
with a callback delegate with an Object argument that will process your
work.

System.Net.Mail.MailMessage message = new system.Net.Mail.MailMessage();
message.To.Add("[e-mail]");
message.Subject = "This is the Subject line";
message.From = new System.Net.Mail.MailAddress("[e-mail]");
message.Body = "This is the message body";
System.Net.Mail.SmtpClient smtp = new System.Net.Mail.SmtpClient("yoursmtphost");
smtp.Send(message);
